It's not a huge deal most days. We're rather cold-blooded around here, so we like a warm house during the summer. We're comfy at 75 or 80. I can even stand 85 fairly well. In the winter we prefer it colder. Its just those super hot days that get to me. But you get creative. Last summer we spent a couple of the hottest days at the dollar movie theater having movie marathons. LoL
